Matter/Anti-Matter in a Vacuum

[keeney123]

TL;DR Summary

Question on the Energy produced and direction of that Energy.

I do not know if this is the place to post this. I am not a great physicist. Actually, I was an Electronic/Electrical Technician before I retired.

I learned that the vacuum of space is filled with matter/antimatter particles popping out of nothing and destroying themselves almost instantly.

My question is are these particles responsible for expanding space?

Virtual particles ("matter/antimatter particles popping out of nothing and destroying themselves almost instantly") are a feature of perturbative relativistic quantum field theory. In contrast, the expansion of the universe ("expanding space") is a feature of certain solutions to the classical Einstein field equations of general relativity. So the answer to your question is no, virtual particles are not responsible for the expansion.
